Usual when you feel a “jolty” earthquake, you’re closer to the epicenter. The farther away you are, the more “rolly” it feels. I felt the Landers quake (7.3) like being on a slow moving boat. I actually got a tiny bit seasick. I was like 150 miles away.
For the Whittier Narrows quake (5.9) I was sitting almost directly on the epicenter. It was very jolty. I was standing in the parking lot for several aftershocks, and it was the first time I felt the ground actually bounce under my feet. Freaky.
Nah, I was just rubbing her feet and trying to wake her up.
I’ve sort of been pondering this. With out checking, this earthquake was centered closer to Boise than the 83 quake. But still probably within 70 miles by the bird. I’m pretty sure its down to different types of seismic waves but could be wrong. Back then I was in a classroom of a (i dunno 40 or 50 year old at that time?) Brick and masonry jr. High school on the second floor. I wonder if or how much that would affect the motion I experienced.
Eta, 83 quake was near Challis ID, which 117 straight line miles from Boise and 40 straightline miles from Stanley. Is that a big enough difference to change which waves reach you or when or however that works (kinda rather lacking on seismology knowledge )
Priorities. Earthquake safety vs social distancing.
The only time I felt the ground bounce under my feet was at a Coheed and Cambria set in the Warped Tour in the late 2000s when the whole crowd was jumping up and down in unison. For some reason it hasn’t happened since, I guess the ground was just the right firmness and the crowd small enough that their waves didn’t interfere with each other.
Speaking of ground bouncing, while in the Army, stationed in California, I was friends with a girl who was from Alaska, and went through the Good Friday Quake of 1964. Her family managed to get outside and clutchec the ground. She said she say the ground rippling like water on a lake. The disaster flick Earthquake had just come out, and she said the noixe the speakers made was like what she heard, but not as steady.
I was at a dance party in an apartment once, and the beat of the music matched the fundamental frequency of the floor.
And you won’t always feel earthquakes, and you’ll sometimes feel things that aren’t earthquakes. Cleveland had one in the early 80s (context clues would put the memory in 1983, but that doesn’t seem to match the historical record) that apparently everyone but me felt. The school sounded the tornado-drill alarm (because we don’t have earthquake drills), and I figured that it was just a drill, and that everyone talking about the earthquake was just joking at me. Then I got home, and horrors, my mom and sister were in on the joke, too, and that was just too cruel. I didn’t believe that there was actually an earthquake until I called up the director of the Natural History Museum and heard it from him.
East Africa’s been dealing with the locusts forever now. Since, like…fuck…The Middle Of March.
I think it’s time for frogs/toads. I think that’s scheduled to go down in Australia.
One horseman at a time, please.
Wrong. The epicenter was exactly 100 miles from Yellowstone Lake. That’s close.
The tremors were felt at least as far away as Puget Sound, Sandpoint (near Idaho-Canada border), Bozeman Montana, and Salt Lake City.
